7> **HARD GATE** — **HARD GATE** — Before shipping, ALL enforcement checks must pass: lint, typecheck, tests, coverage gates. Do NOT disable or skip checks to get to green.

10Apply the F.I.R.S.T rubric per CONVENTIONS.md §Tests to evaluate and improve tests.
11 
12This skill is typically invoked internally by `develop-tdd` during the test-writing phase. It can also be run standalone on an existing test suite.
13 
14## Modes
15 
16- Default: full F.I.R.S.T audit (all 5 criteria)
17- --quick: Check Fast, Independent, and Self-Validating criteria only (per CONVENTIONS.md §Tests). Used by build-epic step 6 as a mechanical gate after audit-code. Skips Repeatable and Timely which require contextual judgment.

19## The F.I.R.S.T Rubric
20 
21See CONVENTIONS.md §Tests for the canonical F.I.R.S.T rubric definition, checklists, and fix patterns.
22 
23Mechanical self-check (runs before reporting audit complete):
24 
25```bash
26grep -q '## Tests (F.I.R.S.T' CONVENTIONS.md
27grep -qE 'Fast|Independent|Repeatable|Self-Validating|Timely' CONVENTIONS.md
28```
29 
30Each criterion must be explicitly addressed in the audit report with pass/fail per test file reviewed.
31 
32## Applying the rubric
33 
34For each failing criterion:
351. Identify which tests violate it
362. Describe the fix
373. Apply the fix
384. Re-run the suite to confirm it still passes
39 
40Report: "F.I.R.S.T audit complete. X criteria passed, Y fixed."
41 
42## Verify
43 
44→ verify: `grep -q '## Tests (F.I.R.S.T' CONVENTIONS.md && grep -qE 'Self-Validating|Repeatable' skills/enforce-first/SKILL.md && echo OK`
